IMPROVEMENT-IN STOVE-PIPE WALL-THIMBLES Specification forming part ofLetters Patent No. 189,071, dated April 3, 1877; application filedSeptember 25, 1876.

To all whom it may concern Be it known that 1, CHARLES STREIT, ofCincinnati, Hamilton county, State of Ohio, have invented an Improvementin Stove-Pipe Wall-Thimbles, of which the following is a specificationMy invention has for its object the construction of a thimble forpermanent setting in the flue-wallof a building, which shall have thecapacity of contraction, to securely embrace and hold stove-pipes ofvarious sizes that may beiutroduced therein, and thus avoid theannoyances and accidents incident to the use of the unyielding thimbleand loose pipefitting now prevalent.

My invention consists of a thimble composed of two or more essentialparts, one of which is the exterior shell for attachment to the wall,and the other a reducible sleeve, so connected and constructed that,while it will preserve a sufficiently tight joint between itself and thepermanent thimble, itlwill also tightly embrace and make a sufficientlytight joint between itself and the stove-pipe which may he introducedtherein.

My invention further consists of a peculiar device for contracting andfirmly securing the reducible sleeve.

Figure l is a perspective view of my wallthimhle detached, and Fig. -2 aperspective view of the same secured in the wall and embracing thestove-pipe.

A is a thimble provided with flanges a a, by which it may be permanentlysecured in the aperture for the entrance of the pipe into the wall.Inside this ring I provide a sleeve, B, which may be in one, two, ormore pieces. It is' at its inside edge riveted to the outer ring, therivet or rivets a. being somewhat loose, so that the sleeve B may swingin a vertical plane to adapt itself to differences in location of pipesintroduced therein. The sleeve, as shown in the drawing, is composed oftwo pieces, and to one of them I attach a two-part bale, G, the parts ofthe bale being connected together by a curved screw-rod and nut,D E, bywhich the sleeve may be contracted and secured. It is obvious that thesleeve may be in one piece, riveted by a single rivet, to swing in theouter ring, and, while maintaining the swinging capacity, it may be madeto reduce to a certain fixed size, and be permanently secured in thatposition for the entrance of a given-sized pipe always. This would thenembrace my feature of swinging, to adapt the sleeve to thevaryinglengths of stove-pipe, from the stove to the upper elbow, butwould not embrace the separate feature of adaptability to close on theperiphery of various sizes of pipe.

I claim- 1. A thimble, A, for stove-pipe, having a swinging sleeveattached therein, substantially as and for the purpose specified.

2. The combination of shell or ring A, and reducible sleeve B,constructed and operating substantially as and for the purposespecified.

3. In combination with the ring A and reducible sleeve B, the bale O.and screw-fast ener D E, connected and operating substantially as andfor the purpose specified.

In testimony of which invention I hereunto set my hand.

CHARLES STREIT.
